Though Kemp, 25, and Rihanna, 21, were spotted smooching and snuggling together, the hunky jock said the Grammy winner is "just a friend, a good friend of mine." He added, "We went down to Mexico and had fun together."

The 25-year-old baseball pro has a lot riding on him.

Considered one of the best center fielders in the league, Kemp was just rewarded with a two-year, $10.95 million contract after he won Gold Glove and Silver Slugger awards.

But will his playing the Hollywood field get in the way of his professional game?

Dodgers manager Joe Torre, who has worked with Derek Jeter during his high-profile hook-ups, doesn't think so.

"When I see or sense it's become a distraction, that's when I'll say something," Torre said. "I don't like to anticipate problems."
